Abstract: A decorative or landscape pond system which includes the skimmer assembly and a substantially horizontally-positioned, submersible and rotary pump in the skimmer assembly and supported on a bottom wall thereof. The skimmer assembly includes a side opening and a net and mat filter positioned within the skimmer below the opening and above the bottom wall. The pump is in elongated structure having an inlet/outlet section at one end, an electrical inlet section at the other end and an elongated electric motor section there between. A lubrication section is positioned between and sealingly engages the inlet/outlet section and motor section. A plurality of O-ring and face seals are provided for sealing the sections. The securement of the sections is either radially outward or radially inward of the O-rings and face seals to minimize leakage between sections or into the pump itself.
